Treatment from the novel
A Clockwork Orange that was supposed to prevent our
chelovek friend
Alex from wanting to perform a little of the
ultra-V.
The idea was to strap Alex in the chair, prop his eyelids open, drug him with nausea-inducing drugs, and subject him to hours of films filled with scenes of unspeakable violence. The reinforcement made it so whenever Alex saw anything violent, he would immediately throw up. This was seen as a way to rehabilitate a hardened criminal. It also had the unfortunate effect of causing Alex to be repulsed by the old Ludwig Van.
It would be giving away the ending if I let you know whether this actually worked or not.
